Green Roof Systems

Research worldwide has shown that green roofs limit the impact of climate change, underlining the valuable role they play in sustainable design. They reduce heat transmission from rooftop to habitable space below, lower ambient temperature, mitigate urban heat island effect, reduce rainwater runoff, and improve air quality and aesthetics.

Water retention – precipitation is retained on site reducing run-off to storm water systems.

VersiCell

VersiCell is an efficient lightweight, high strength, interlocking drainage module that captures and transports high water volumes and protects the waterproofing membrane. VersiCell is Ideally suited for use in intensive green roof systems where load weight bearing capacity and efficient drainage is important.

Unaffected by moulds and algae and good resistance to oils, acids, alkalis and bitumen

Service Temperature

-20ºC to 120ºC

VersiDrain 30

VersiDrain 30 is a lightweight, cost-effective water management tray used below the growing media that functions to store and drain water and to protect the waterproofing membrane. The high water storage capacity of the cells coupled with efficient discharge capacity ensures effective capillary irrigation, eliminates the possibility of water-logging, reduces irrigation frequency and minimizes fertiliser runoff and usage.
